M ECHANICAL DIRECTORY.

SPECIFICATION forming part of Letters Patent N 0. 697,379, dated April 8, 1902.

' Application filed October 23,1900. Serial No. 34,080. (No model.)

To aZZ whom it may concern.-

' siding at Los Angeles, in the county of Los Angeles and State of Oalifornia,have invented new and useful Improvements in Mechanical Directories, of which the following is a specification.

This invention relates to a mechanical directory of the type heretofore invented by me and set forth in certain applications for patents which I have filed in the United States Patent Office as follows: Serial No. 676,132, filed April 1, 1898, renewed August 1, 1900, Serial No. 25,591; Serial No. 684,712, filed June 29,1898, renewed August 1, 1900, Serial 'No. 25,592; Serial No. 705,446, filed February Another object is to supply an index of eX-' tremely slow movement relative to the movement of the directory strips or ribbons.

The accompanying drawings illustrate my invention.

Figure I is a perspective view showing the mechanism of my novel mechanical directory inits case, fragments of which case are broken away for clearness of illustration. The directory strips or ribbons are omitted from this View for clearness of illustration of the mechanism.- Fig.1l is an elevation of the reversing mechanism, portions of the sprocketchains being omitted. Fig. III is a section on line III III, Fig. II. Fig. IV is a perspective detail illustrating one of the lever-dogs. Fig. V is a side elevation viewed from the left of Fig. I, showing the index-operating mechanism and also showing by dotted lines the arrangement of the directorystrips upon their appropriate rollers and idlers or guides. Fig. VI is a front elevation of the directory.

a a b 1) indicate the several rollers of two pairs of rollers.

'0 indicates a strip fastened at its ends, respectively, to the rollers a a of one pair. 0' indicates a strip fastened at its ends, respectively, to the rollers Z) Z) of the other pair. The sprocket-chain e and sprocket-wheels 1 2 constitute means operatively connecting one roller a of one pair with one roller 1) of the other pair for their simultaneous operation. The sprocket-chain e and sprocket-wheels 1 2 indicate like means operatively connecting the other roller (1 of the one pair with the other roller Z) of the other pair for their simultaneous operation. f constitutes means for driving one of said first-named connected rollers. 9 indicates a clutch for connecting and disconnecting said meansf with and from its said roller a. f indicates means for driving one of saidsecondnamed connected rollersviz., roller a. g indicates a clutch for connecting anddisconnecting said means f with and from its roller 0.. It indicates a shaft constituting a prime mover for operating the directory. i indicates a sprocket-chain constituting means for operatively connecting said shaft h with both of said sprocket-wheels ff for simultaneously driving them. A lever connectionj is provided for connecting and disconnecting the clutches g g. 76 indicate reversely-ar ranged spring-pressed dogs on'said lever con nection on opposite sides of said shaft h. 071

indicates tappets connected with the shaft h to rotate therewith and arranged to move across the path of said dogs, Wherebywhen the shaft is rotated in the one direction said tappets operatively engage one of said dogs to operate the leverj, and the other dog will yield to allow the tappets to pass. The tappets m are connected with the shaft 77. through suitable means-viz., the master-wheel n of shaft h, which drives the sprocket-chain 2' to drive the roller driving wheels f f. The sprocketchain 71 is trained around the master sprocketwheel a and the driving sprocket-Wheels ff, so that when the shaft is rotated in one direction the lever and rollers will be operated in one direction, and vice versa when the shaft is rotated in the other direction.

0 indicates an annularly-grooved member upon the shaft h. The lever j is mounted on said member 0 by means of set-screwsp, which fit into the groove 0 and pivot the lever j to the shaft 71, but at the same time allow the lever j to vibrate on the shaft to throw one end of the lever in one direction and the other The sprocket-wheel end of the lever in the other direction when the shaft 71 is rotated to cause the tappets m to engage the dogs, thereby to operate upon one of the dogs to throw one end of the arm in one direction and the other end of the arm in the reverse direction, the other dog being arranged to yield to the pressure of tappets to let them pass without throwing the lever. 1 indicates springs for holding said dogs in place in the path of the tappets m and to allow the dogs to spring out of the way when the tappets engage them from the non-operative side. The dog 7.1 will operate to throw the upper end of the lever away from the rollers, thus to disconnect the clutch 9 when the prime mover 7L is rotated over toward the front, and the dog 7;. yields to the tappets on when the prime mover it is turned in said direction. \Vhen the prime mover is turned in the reverse direction, the dog 7.1 will be Operated upon by the tappets to throw the lower end of the lever away from the rollers and the upper end of the lever toward the rollers, thus connecting the clutch g and disconnecting the clutch g. Said lever j is operatively connected, through sprocket-wheels ff, to appropriately connect and disconnect the clutches, respectively, of such sprocketwheels. The lateral movement of the shifting s in'ocket-whecls ff need be only very slight in order to allow the proper operation of the clutches g g.

Referring to Figs. V and VI, 0* indicates an index-strip. s and s indicate two rollers, upon which said index-stripis mounted to be wound and unwound from roller to roller. Said strip is carried over the guides 25 t to exhibit the index-strip through the opening a of the case r. 10 indicates a bevel-wheel on one of the directory-rollers a. :1: indicates a worm gear-wheel on one of the index-strip rollers. indicates a shaft furnished with a bevel-gear e at one end, meshing with the bevel-gear '1! on the directory-strip roller, and said shaft is also furnished with a worm 3, engaging the worm-gear a: on the index-roller. l indicates a sprocket chain led around sprocket-wheels 5 5, respectively fastened to the index-rollers s 3, whereby said indexrollcrs are connected to simultaneously rotate. Vhen in the operation of the machine the roller a turns in one direction, the indexstrip will be moved very slowly in one direction, and when the roller a is turned in the other direction the index-strip will be driven very slowly in said other direction.

What I claim, and desire to secure by Letters Patent of the United States, is-

their simultaneous operation; means for driving one of said first-named connected rollers; a clutch for connecting said means with and disconnecting it from said roller; means for driving one of said second-named connected rollers; a clutch for connecting said means with and disconnecting it from its roller; a shaft; means operatively connecting said shaft with both ofsaid roller-driving means for simultaneously driving them; a lever connection for connecting and disconnecting said clutches; reversely-arranged dogs on said lever connection at opposite sides of the shaft; and tappets connected with said shaft to rotate therewith and arranged to move across the path of said dogs whereby when the shaft is rotated in the one direction, said tappets operatively engage one of said dogs to operate the lever connection 'in one direction to connect one of said clutches and disconnect the other of said clutches, and when the shaft is rotated in the otherdirection said tappets will operate the other dog and throw the lever to connect the other clutch and disconnect the first-named clutch.
